On the planarity of the -zero-divisor hypergraphs
Let be a commutative ring with identity and let be the set of all -zero-divisors in and an integer. The -zero-divisor hypergraph of , denoted by , is a hypergraph with vertex set , and for distinct element in , the set is an edge of if and only if …
